Changeset 12930 for OpenSceneGraph/trunk/examples/osgmanipulator/osgmanipulator.cpp

Timestamp:

01/31/12 11:56:52 (16 months ago)

Author:

Message:

Improved the handling of osgManipulator::Constraint, DraggerCallbacks? and Command so that they now use a Visitor Pattern

to ensure the correct methods on constraints and callbaks are called for each Command. Also fixed the handling of

Constraints when applied to composite Draggers.
